Hi,
first of all welcome to the list!
we (UniBasel) use NAV for quite some while now and are very pleased with the possibilities NAV gives us. We use Debian as OS with the following Setup:
root@urz-nav:~# uname -a Linux urz-nav 2.6.32-5-amd64 #1 SMP Fri May 10 09:44:53 UTC 2013 x86_64 GNU/Linux root@urz-nav:~# cat /etc/debian_version 6.0.7 root@urz-nav:~# dpkg -l | grep nav ii nav 2+3.14.15-1 Network Administration Visualized
A problem we have since a while is that our system is permanently under a lot of load (mostly CPU bound) and we haven't really found a way to reduce the pressure. The hardware we use is a hp blade (ProLiant BL460c G6) with:
Intel(r) Xeon(r) Processor X5550 (4 Cores/ 8 Threats) (8M Cache, 2.66 GHz, 6.40 GT/s Intel(r) QPI)
and: root@urz-nav:~# free total used free shared buffers cached Mem: 12321700 11673596 648104 0 387768 9123748
At the moment we have 1460 active Devices (mainly Cisco Switches). Around 30 or 40 are OVERDUE in: https://urz-nav/report/lastupdated
So my question is, do you have any good experience with HW-systems that are actually dealing with this amount of devices or is there any tuning possibility (without losing functionality) we could try to reduce the pressure on the system?
Thanks in advance, Mischa Diehm
